2 Claims.

This invention relates to a bottle cap.

It is an object of this invention to provide an improved bottlxcap which is relatively simple and inexpensive in construction and ecient in use.

Another object of the Apresent invention is to provide a new and improved closure cap for bottles and analogous containers by means of which such a container may be efiiciently sealed while still permitting the seal to be broken an'd the cap removed from the container so that the contents of the latter may be used or. removed in part, whereupon the lower part of thel cap may be restored to its initial or position of use so as to act as a closure for the bottle or like container during the time the contents of the latter remain in the container for use, as desired, from time to' time.

Another object of the present invention is .-U to provide a bottle or closure cap which may be removed from a bottle, or like container to which it is fastened, by hand and without the use of any tool or implement. x

An'additional object of the present invention 5 is to provide a new and improved bottle cap which is particularly adapted for use upon bottles and analogous containers in which liquids, such as beverages and the like, are contained under pressure, that is, under the pressure of gas stored therein.

It will be seen, from the foregoing object that the new closure cap is particularly intended for use upon bottles and analogous containers for food product's and the like from which only a 3,-, part of the contents is removed at one time after the seal has been broken and the remainder of the contents are retained in the container for use from time to time.

Another object of the present invention is,

.10 therefore, to provide a new and improved closure cap for bottles and analogous containers which are used in the manner hereinbefore set forth.

Another object of the present invention is to construct the new closure cap of two parts and in such a manner that the same may be readily .55 The invention consists in the novel combina- 1937, Serial N0. 158,034

tion and arrangement of parts t0 be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing showing the preferred form of construction, and in which: 5

Fig. 1 is a side elevational view showing a preferred form of the new closure cap attached to the neck of a bottle of conventional design;

Fig. 2 is an enlarged top plan View of the cap shown in Fig. l; A,

Fig. 3 is a central vertical sectional view, on line 3 3 in Fig. 2, of thecap shown in Fig. 2, and showing the same in applied position;

Fig. 4 is a front elevational view of the upper part of the 'new closure cap shown in Figs. l, 2 and 3;

Fig. 5 is a perspective view of the upper part of the new closure cap; and

Fig. 6 is a front elevational view of the lower part or base of the new closure cap.

A preferred form of the new closurecap is shown in the drawing, being thereingenerally indicated at I0, and is'shown as applied to the neck II of a bottle I2 although it is tobe understood that the present closure cap may be applied to the necks of other analogous containers including cans. The new closure cap Il! is made of two parts and includes a lower cap part I3` (Fig. 6) and an upper cap part I@ (Fig. 5). The vlower part I3 of the cap I0 includes a disclike portion or body I5 and integral with, and depending from, this disc-like portion I5 of the lower part I3 of the cap Il), and extending around the annular marginal edge of the same, is a skirt I6 which is provided with a series of corrugations il, which are, of course, conventional in the art of closure caps. Provided in this disc-like portion of the lower part I3 of lthe cap I Il is a slit or slit-like opening I8 which extends, radially, from the center of the same outwardly to the periphery thereof and then downwardly through the skirt I6; that portion of the opening l'8 which extends downwardly through the skirt i6 being ared or splayed and being indicated at I9 (Fig. 6). The lower cap -45 part I3 also includes a sealing disc 25, which may be made of cork or other suitable material, and which is arranged within the skirt 2l and under the disc-shaped portion I5.

The upper part it of the new closure cap I 0 includes 'a tab portion 20 and integral with this tab portion 20 is a depending flange or skirt 2l which is provided with a Series 0f corrugations 22, and formed integrally with the Skirt portion 2l of the lower cap part It, at the lateral edges 55 of the said skirt 2 I, are two spaced and upwardly curved lugs 23, these lugs 23 providing a gripping means for detachably attaching the two cap parts I3 and I4 together.

Formed in the tab 20, and extending around the marginal edge of the same, is a reenforcing ridge or flange 24.

In the use of the new closure cap the upper and the lower parts I3 and I4 of the same are fastened together, prior to the bottle-capping operation, that is, the parts I3 and I4 of the cap are formed separately and are then attached or latched together by projecting the lugs 23 of the upper cap part I4 up under the skirt I6 of the lower cap part I3, on opposite sides of the mouth I9 of the opening I8 in the lower cap part I3. Accordingly. when thus assembled or attached together, the cap partsvl3 and I4 are applied simultaneously in position of use upon the neck of a bottle or analogous container by means -of a bottle capper or forming die. Accordingly, when the cap parts I3 and I4 are arranged upon the neck of a bottle or analogous container and pressure is applied to the same during the capping operation, the lugs 23 on the upper cap part I4 will be forced into close engagement with the skirt I6 of the lower cap part I3, thereby binding the said cap parts together and upon the bottle.

It Will be noted that when the cap parts I3 and I4l are thus assembled together and arranged upon the neck of a bottle, the tab 20 is forced down over the disc-like portion I5 of the lower cap part I3, thereby securely closing that portion of the slit or opening I8 which extends through the disc portion I5 of the lower cappart I3. At the same time the skirt portion 2| of the upper cap part I4 is urged into engagement with the skirt portion I6 of the lower cap part I3, so as to close the opening I9 in the latter, and the gripping means or lugs 23 are urged into gripping engagement with the skirt portion I6 of the lower cap part I3, at opposite sides of the opening I9 in the latter, so as to hold the two cap parts together and upon the container to which they are applied.

When it is desired to remove the new closure cap from a bottle or analogous container, so as to remove either a part or all of the contents thereof, this may be accomplished manually, without the use of any tools or implements, by inserting the ngernails under the tab 28 and between the latter and the disc portion I5 of the lower cap part I3, and lifting upwardly on the tab 20, whereupon, by pulling the tab 2U to the right (Figs. l and 2), that is, radially outwardly along the axis of the slit I8, the upper cap part I4 may be separated from the lower cap part I3, it being understood that the seal is not, at this time, broken by reason of the fact that the cork or analogous disc 25, which forms a part of the lower cap part I3, still closes that portion of the opening I8 which extends through the disc I5. The lower cap part I3 may then readily be removed from the neck of the container, by inserting the ngernail under the skirt I6 of the same, and then, lifting upwardly thereon by means of the thumb and index iinger, since the slit I8 enables the lower cap part I3.to be spread or expanded slightly so that the skirt I6 thereof may be raised up over the ange or bead 26 on the neck I I of the bottle or other container.

It will thus be noted .that the cap parts I3 and I4 may be removed from the neck of a bottle Without the use of any tool or implement, as described above, although these parts may likewise,

if desired, be removed from the bottle by means of a suitable tool or implement,- such as a screw driver orbottle cap remover.

Accordingly, when it is desired to reseal or close the container I2 this may be accomplished by manually forcing the lower cap part I 3 down onto the neck II of the container, this being rendered possible by reason of the slit I8- in the disc I5 which permits the skirt I8 of the lower cap part I3 to be spread or expanded slightly so that it will pass the bead 26, whereupon when the thus divided skirt 2I is forced past the bead 26 it will, by reason of its own resiliency, spring back into its initial position, thus resealing the container. It is to be noted, in this connection, that both the upper and lower cap parts I4 and I3, respectively, are preferably made of metal of the character usually employed in making closure caps.

From the foregoing description it will be seen that the present invention' provides a new closure cap for bottles and the like which is simple in construction and efficient in use by reason of the fact that it may be removed by the hand, without the use of any tool or implement; and that it may be used repeatedly on a container to which it is applied and as long as it is desired to keep the container closed and the contents thereof covered. Hence, it will be seen that the present closure cap is particularly adapted for use in connection with bottles and analogous containers, such, for example, as are used for containing beverages under the pressure, that is, under the pressure of the gas dissolved therein; and from which containers only a part of the contents is removed after the seal has been broken, whereupon the lower cap part I3 may be reinsertedonto the neck of the bottle or analogous container so as to keep the same closed and covered until such time as the contents thereof have beerrcompletely removed.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modication, without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desired to avail myself of such variations and modications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
